Marks: +1, -0

In the following table, the readings of an odometer at different times of a journey are given :

The speed of the vehicle in metres per second is

Solution:

Total distance travelled is

(6712-6640)=72{km}

Total time taken

=2hr

Speed in m/sec

=\;\;{\;\text"Distance"\;}/{\;\text"Time"\;}=\;\;{72×1000{m}}/{2×60×60}=10{m}/{sec}
